2 Claims. (Cl. 112'-240) This invention relates to a sewing machine foot which is adjustable to the right or left and also backwards or forwards.

A sewing machine foot must be adjusted so that the needle does not rub againstit, otherwise either the needle or the thread will break. Present machines provide for right and left adjustment, but not for forward and backward adjustment. And to adjust to the right or left, a plate has to be unscrewed and removed from the machine for access, and then the foot bar screw must be loosened before the adjustment can be made, then the plate must be screwed back on, which actions are unnecessary with the foot herein shown and described, and are also unnecessary for the other two mentioned adjustments, it being necessary only to loosen two screws on the foot to accomplish the four mentioned adjustments.

The drawings illustrate the invention, and in these:

FIGURE 1 is a front view of the foot as attached to the foot bar;

FIGURE 2 is a view from the right'side of FIGURE 1;

FIGURE 3 is a back view of FIGURE 1 with the omission of the connector and foot bar;

FIGURE 4 is a plan view of the foot proper;

FIGURE 5 is an enlarged cross section taken on line 55 of FIGURE 2;

FIGURE 6 is an enlarged longitudinal section taken on line 6-6 of FIGURE 3; and

FIGURES 7, 8 and 9 are respectively enlarged bottom, side and top views of a pivoted block forming part of the foot.

Referring to the drawings for a detailed description, the numeral 10 indicates the foot proper; it includes the toes 11 and 12 which are spaced to receive the machine needle, one being shorter than the other for gaging purposes, as known. Back of the toes, the foot proper is machined to form an opening 15 to receive a block 17 between the resulting sides 18 and 19 of the foot proper, said opening extending from the front to the rear of that part of the foot proper which is back of the toes. The block 17 is pivotally mounted in said opening by a threaded bolt 21 which passes through the block and through the mentioned sides 18 and 19 and threadedly engages the latter side.

A vertical recess 25 is'formed in therear portion of block 17, said recess opening from the bottom of the block to receive the upper portion of a compressed coiled spring 27. The lower portion of said spring is received in arecess 28 formed in the foot proper and in alignment with recess 25. The spring thus being boxed in, it is held in place, as contrasted with present constructions in which the spring becomes dislocated due to wear. Said spring, located as it is behind the pivot 21, presses upwardly against the rear portion of block 17.

A cylindrical rod 30 has the under surface of its forward end portion 30A fiatted'or planed, and that end United States Patent 0 portion is secured to the top of block 17 by means of a threaded bolt 32, and the rod extends backwardly to the rear of the foot proper, being reduced in diameter at 30B, By merely loosening the bolt 32, the interconnected block 17 and the foot proper may be turnedto the right or left for adjustment relative to the machine needle, the bolt being then tightened.

A connector 35 is slidably mounted on the rod 30 to provide for forward and backward adjustment of the foot relative to the machine needle. To fasten the connector to the rod in a desired position, the lower part of the connector is split at 37 from front to back (FIGURE 1) and opposing parts adjacent the lower end of the connector, are each bored semi-cylindrically, thereby providing a cylindrical hole to grippingly receive the rod 30, said opposed parts being tightened against the rod by a threaded bolt 39. The connector 35 is vertically recessed in its upper end portion, as indicated at 42, to receive the lower end of the usual spring-loaded foot bar 43, said recess being open at the top and one side, and on the opposite side is slit part way down from the top. The connector is fastened to the foot bar by a transverse screw 45 which rests on the bottom of said slot and threadedly engages the foot bar. Thus the foot of my invention may be adjusted forwards and backwards and to the right and left.

What is claimed is:

1. A sewing machine foot of the character described comprising a foot proper with toes spaced to receive a needle, a block pivotally mounted on the foot proper, a

rod, a releasable fastener securing the forward portion of the rod to the block, means permitting turning of said block and foot proper to the right or left about said releasable fastener relative to said rod, the latter extending rearwardly beyond the foot proper, a connector slidably mounting said rod so that the foot proper, the block, and the rod, may be moved forwards and backwards relative to the connector, and releasable means for fastening the connector at a desired posit-ion of the rod.

2. A sewing machine foot of the character described, comprising a foot proper wit-h toes spaced to receive a needle, a block pivotally mounted on the foot proper, a rod, a releasable fastener securing the forward portion of the rod to the block, means permitting turning of said block and foot proper to the right or left about said releasable fastener relative to said rod, the latter extending rearwardly beyond the foot proper, a connector'slidably mounting said rod so that the foot proper, the block, and the rod, may be moved forwards and backwards relative to the connector, and releasable means for fastening the connector at a desired position on the rod, said block having a vertical recess back of said pivotal connection of the block to the foot proper, the latter having a recess in vertical alignment with the recess in the block, and a compressed spring in said recesses pressing upwardly against said block.
